Extensive efforts have been made in the research and development of smart textile systems in recent years. One of these developments in smart materials is shape memory applications. Shape memory materials (SMM) are smart materials that can remember and recover substantial programmed deformation upon activation and exposing to an external stimulus such as chemicals, temperature, pH, light, a magnetic field, etc. Shape memory materials have been used in many areas and textile application of this technology has covered a wide usage recently. Today's textile concept isn't the similar to past and expectations of people from textile have been changing more and more. In this point, shape memory materials can answer these needs in textile due to its smart features. Shape-memory materials can be used in textile as clothing, yarn and fabric. The application possibilities are only limited by our imagination and creativity, so shape-memory productions have been able to gain a different aspect to textile.

In present study, electronic vests were designed by using conductive textile material and electronic circuits. The objective was to sense armed assaults and transmit the coordinates and position of gun fire instantly to the headquarters. Another objective is to provide instant emergency respond for injuries at vital sections of the body and to capture perpetrators quickly. To reach the desired targets, silver-coated conductive yarn, polyamide plain weave and various circuit components were used. Silver-coated conductive yarn was used to form sensor unit of the electronic vest and stitched over polyamide fabric in 3 mm intervals. Main vest section was prepared in medium size and conductive-yarn sensor unit was installed to the vest with a velcro system. Classical and Surface Mount Device (SMD) circuit technologies were used in circuit units to sense bullet intrusion and transmit the case to operational center. Two different circuit designs were tested at a shooting range and the outcomes were assessed and compared for two different circuits. It was observed in shooting tests that both vests were able to sense bullet intrusions in case of an assault and to transmit the shot message with the coordinates and position of the shoot correctly.

In textile sector intuitive non-engineering methods and skill based designer oriented design processes are regarded as appropriate for textile manufacturing. However, design presented by the use of Prescriptive design models concludes to be more direct and rapid when compared to the Descriptive design models. For these reasons, systematic design techniques prove to be more scientific and easy to manipulate when compared to classical intuitive design techniques. Since textile, as an industrial product in essence, has its own design paradigms and scientific background, it has to define its own methodology in an attempt to form a scheduled, programmed and repeatable design process.The primary objective of this research is to provide support to the textile designer during early stages of the design process by using Conceptual Design steps, which can be used as a creative analysis process in textile design problems providing a high level of creativity. The Pahl and Beitz model is employed to investigate critical and complicated design problems of three design projects, each conducted by different student, solving different design requests from different fields of textile sector and thus, each fulfilling different transformation functions and design solutions. The resulting collections are presented and the steps of process are discussed in the Results & Discussion part.

Öz Tekstil, ülkelerin güçlü dinamiklerinden biri olmasının yanı sıra yoğun şekilde insan emeğine ve nitelikli insan gücüne ihtiyaç duyan bir sektördür. Tekstilin alt dallarından biri olan örme, ister triko örme şeklinde bireysel, ev tipi makinelerle küçük atölyelerde, istenirse örme kumaş olarak seri üretime uygun fabrikasyon üretim yapabilmeye imkân veren bir alandır. Her iki üretim şeklinin de temel yüzey yapısını ilmek adı verilen temel yapı birimi meydana getirmektedir. İlmeklerin yan yana ve üst üste dizilmeleri ile örme tekstil yüzeyi elde edilmektedir. Kuşkusuz bu yüzeylerin oluşturulmasında en önemli aşamalardan biri örme tasarımının gerek hayal gücü gerekse bilgi birikimi ile somutlaştırılmasıdır. Ancak kişiden kişiye değişiklik gösteren, farklı beğeni ve beklentilerin karşılanmasını da amaçlayan ürün tasarımı, günümüzde işletmelerin çözemediği temel sorunlardan biri olarak hala yerini korumaktadır. Bu nedenle örme işletmelerinde tasarımcı/desinatör olarak görev yapan kişilerin tasarım problemine bakış açılarını belirlemek ve bu süreçte kullandıkları çözüm stratejilerini ortaya koymak bu araştırmanın temel amacını oluşturmaktadır. Tarama modelinin kullanıldığı bu araştırmada, verilere ulaşabilmek amacıyla öncelikle literatür taraması yapılmış ardından örneklem olarak seçilen örme işletmelerine gidilerek tasarımcılar/desinatörler ile görsel analiz, mekanik gözlem ve yarı yapılandırılmış görüşme teknikleri kullanılarak araştırma verileri elde edilmiştir.
